基于模糊PI控制算法的微电网并网控制策略研究
摘要：由于微电网的逆变输出波形和功率因数效果不理想,本文提出了基于模糊PI控制的双闭环微电网并网逆变控制策略,结合了模糊控制和PI控制的优点,实现双闭环控制。仿真结果表明,新控制策略控制性能良好:并网电流和大电网电压保持同相位,并网功率因数较高,并网电流最大谐波畸变率降低,滤波效果非常理想。

Abstract:In this paper, due to unsatisfactory output waveform of inverter and bad power factor of micro-grid, a double closed-loop control strategy for the micro-grid inverters is presented based on combining the advantages of fuzzy control and PI control to realize double-loop control. Simulation results show that the proposed control method has good control performance, can maintain the same phase of grid-connected current as that of grid voltage, provides higher power factor, reduces the maximum harmonic distortion rate of the grid-connected current, and achieves extremely ideal filtering effect.
